Although Bobbi Kristina has denied that she posted a photo of herself smoking out of a water pipe with a rambling message about drug use, pain and numbness, her family is still concerned about it.

Bobbi Kristina’s Family Concerned After Leaked Pipe Photo
The only child of Whitney Houston and Bobby Brown tweeted about the pic, "I've never posted any photo of me doing anything! This is someone trying to tarnish and make a horrible name for MYSELf. People are insane." Her Instagram account has also been deleted.

Now, her uncle, Gary Houston, told, “When you love someone everything concerns you, so the fact of the matter is we have to get to the bottom of it. I have to find out for myself. I’m in the process of investigating it now.”

He added, “She’s doing very well.”

The 21-year-old recently reunited with her dad for Father’s Day. Her mother passed away in February 2012.
